Answer:
Answer=B
(f+g)(x)=-3x-5
Step-by-step explanation:
f(x)=x+8.
g(x)=-4x-3.
(f+g)(x) means f(x)+g(x),So
(x+8)+(-4x-3)
(add all same terms together)
=(x+(-4x))+(8+(-3))
=-3x+5
so,
(f+g)(x)=-3x+5
Answer:
312 mi/hr
Step-by-step explanation:
Distance = 2184 miles
Time taken = 7 hours
Average speed = Distance / time taken
Average speed = 2184 miles / 7 hours
Average speed = 312 miles per hour
Hence, the average speed Traveled by the plane traveling from Knoxville to Los Angeles is 312 miles per hour

Answer:
Properties of a normal distribution
The mean, mode and median are all equal.
The curve is symmetric at the center (i.e. around the mean, μ).
Exactly half of the values are to the left of center and exactly half the values are to the right.
The total area under the curve is 1.
